HERS ECC Title 24 Group
Homeowner FAQ
Is a “HERS test” the same as an “ECC test”?
Yes. California renamed its HERS field-testing program the Energy Code Compliance (ECC) Program effective January 1, 2026. Contractors and cities use both names for the same required verification.
Why can’t my HVAC contractor just do the test?
Because the law requires independence. The rater’s job is to verify the installer’s work; the same company can’t grade its own homework. That separation protects you.
How long does it take?
Most single-system residential tests take one to two hours on site. Larger projects and new construction take longer; we’ll tell you before we book.
How much does it cost?
You get a straight, all-in quote before anything is booked — the price depends on which tests your permit scope requires. Registry document fees are set by CHEERS and appear as separate line items, so you can see exactly what goes where.
Do I need to be home?
An adult needs to provide access at the start. After that, you’re welcome to go about your day; we’ll walk you through results before we leave or by phone.
My paperwork was filed with CalCERTS — now what?
CalCERTS wound down as a registry; California projects now run through CHEERS. We can re-register your project in CHEERS so your permit can close. It’s a common situation and we handle the registry side for you.
Will you try to sell me repairs?
No. We test, we report, we file. We don’t sell equipment or repairs — which is exactly why our results are credible to your building department.
What areas do you cover?
28 counties across the Bay Area, Sacramento region, and Central Valley. See the service areas page for the full list.
What should I have ready?
Clear access to the indoor and outdoor equipment, registers, and attic or crawl space. If the system is brand new, make sure the installer has finished and the filter is in.
What happens if the test fails?
You receive a written explanation of what fell short. Your installer corrects it, we retest, and the passing result is filed. Your final approval simply waits until then — a failed test costs far less than years of a leaky system would.
